Polypropylene camlock fittings (or cam and groove couplings) are made from polypropylene reinforced with acid-resistant fiberglass, which makes PP Camlock coupling has excellent tolerance to most corrosive acids, bases, fertilizers, solvents, and wastewater. The black polypropylene camlock hose fitting is the best-priced lightweight cam and groove coupling available. Ideal for use in conditions where it is constantly subject to moisture. They are typically used in low-pressure suction or discharge hoses of firefighting pumps, IBC (intermediate Bulk Container) containers, and other applications that need quick connect or disconnect operations. It is widely used in inhalation/discharge hoses for agricultural or industrial applications.
All polypropylene cam & groove fittings are NOT for use with compressed air or gases. Polypropylene dust caps and plugs should not be used in pressure applications.
The working pressure below is measured at ambient temperature. When temperature increases, the operating pressure for polypropylene will decrease sharply.
PP camlock coupling type A
